Lipids are nonpolar molecules because they typically contain long hydrocarbon chains that do not have distinct positive or negative poles. Lipids are composed mainly of carbon and hydrogen, making them hydrophobic and insoluble in water.
No. Hydrogen is an element, which forms the molecule H2. Elements and homogeneous molecules (molecules that are all of one kind) are not considered mixtures; mixtures are by definition heterogeneous. An example is air, which is a mixture of nitrogen, oxygen, carbon dioxide, ozone, water vapor, and dozens of other elements and compounds.
Hydrochloric acid (HCl) is a binary acid compound composed of hydrogen and chlorine atoms. It is a strong acid commonly found in gastric acid in the stomach.
Gas stoves typically use natural gas or propane as fuel. These gases are mainly composed of methane, with small amounts of other hydrocarbons. When the gas is ignited, it produces a flame for cooking.
Citric acid has covalent bonds. It is composed of carbon, hydrogen, and oxygen atoms held together by sharing pairs of electrons. This type of bond is strong, allowing citric acid to maintain its structure and function as an organic acid.
hydrogen
H2O; composed of 2 hydrogen and 1 oxygen
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
Sugar is composed of just three elements: carbon, oxygen, and hydrogen.
This is produced by nuclear fusion
Water is a compound, composed of two atoms of hydrogen for every one atom of oxygen.
The make-up was mainly composed of very high contents of lead.
It is mainly hydrogen with some helium. There are small amounts of other gases particularly methane.
Saturn is a gas giant planet composed mostly of hydrogen and helium. It does not have a solid surface made of rock like Earth. The outer layer of Saturn is mostly composed of hydrogen and helium with trace amounts of other elements.
The gases that make up Uranus' atmosphere is mainly hydrogen, helium, and methane.
The curve that currently contains most stars on the HR diagram is called the "main sequence". It consists of those stars that fuse hydrogen-1, converting it into helium-4.
Water is composed of molecular bonds, but forms hydrogen bonds with other water molecules. Hydrogen bonds are not actual bonds, but they cause an attraction between the water molecules, which is why water is adhesive.
